Nontypeable Haemophilus influenzae Has Evolved Preferential Use of N-Acetylneuraminic Acid as a Host Adaptation

open access: yesmBio, 2019
Nontypeable Haemophilus influenzae (NTHi) is a Gram-negative bacterial pathogen that is adapted exclusively to human hosts. NTHi utilizes sialic acid from the host as a carbon source and as a terminal sugar on the outer membrane glycolipid ...

Reduced Complement and Granulocyte Activation by α‐Gal Knockout Porcine Pericardium for Bioprosthetic Heart Valves: A Pilot Hemocompatibility Study

open access: yesJournal of Biomedical Materials Research Part A, Volume 114, Issue 7, July 2026.
Genetically modified, α‐Gal‐depleted porcine pericardium and wild type tissues are investigated for hemocompatibility and material properties such as mechanobiology and ECM profile to carve out the suitability of the gene‐modified tissue as material for biological heart valve prostheses. ABSTRACT Xenogeneic pericardium is the main source for biological

Advancements in Mass Spectrometry‐Based Glycomics in Food and Nutritional Science

open access: yesMass Spectrometry Reviews, Volume 45, Issue 4, Page 829-850, July/August 2026.
ABSTRACT This review highlights advancements in mass spectrometry (MS)‐based glycomics in food and nutritional science. Carbohydrates, which are vital for human health, exhibit complex structures, making their analysis challenging. MS has become an indispensable tool for elucidating the structures of carbohydrates, including glycans, through soft ...

Electrochemical Evaluation of Tumor Development via Cellular Interface Supported CRISPR/Cas Trans-Cleavage

open access: yesResearch, 2022
Evaluating tumor development is of great importance for clinic treatment and therapy. It has been known that the amounts of sialic acids on tumor cell membrane surface are closely associated with the degree of cancerization of the cell. So, in this work,

An In Silico Functional Analysis of Non-Synonymous Single-Nucleotide Polymorphisms of Bovine CMAH Gene and Potential Implication in Pathogenesis

open access: yesPathogens, 2023
The sugar molecule N-glycolylneuraminic acid (Neu5Gc) is one of the most common sialic acids discovered in mammals. Cytidine monophospho-N-acetylneuraminic acid hydroxylase (CMAH) catalyses the conversion of N-acetylneuraminic acid (Neu5Ac) to Neu5Gc ...

Xenotransplantation Literature Update: January–June 2026

open access: yesXenotransplantation, Volume 33, Issue 4, July/August 2026.
ABSTRACT In the first half of 2026, xenotransplantation advanced through refinement rather than dramatic new clinical milestones. Clinical studies described graft physiology, immune infiltration, complement activation, coagulation incompatibility, and early function in living recipients, decedent models, and clinical islet xenotransplantation ...

Gene expression and pathway analysis of effects of the CMAH deactivation on mouse lung, kidney and heart. [PDF]

open access: yesPLoS ONE, 2014
N-glycolylneuraminic acid (Neu5Gc) is generated by hydroxylation of CMP-Neu5Ac to CMP-Neu5Gc, catalyzed by CMP-Neu5Ac hydroxylase (CMAH). However, humans lack this common mammalian cell surface molecule, Neu5Gc, due to inactivation of the CMAH gene ...
